CARRIAGE-POLE. y

srn'crrrcn'rroN forming part of Letters Patent No.' 524,826, aerea August 21', 1894.

` Apllimion led January 3,1894.V sereine. 496,107. (No man To all whom it may coneerm Be it known that I, NATIEIAN L. HOLMES, of Racine, in the county of Racine and State of Wisconsin,'have invented certain new and useful Improvements' in Carriage-Poles; and I do hereby declare that the `following is a full, clear, and exact description thereof, reference being had to the accompanying drawings, and to the letters of referencemarked thereon, which form a part of thisspecification.

This invention has for its object to provide a construction `in carriage poles which shall be at once strong, neat and cheap. In an embodiment of lmy invention the arms and braces of the carriage pole are yof channeliron, and the invention consists in the arrangement of the channel-iron members channel to channel with the edges of their iianges in contact 4with each other or with the tongue or proximate, at those points where they are united, and the combination with said members, s0 arranged, of iilling blocks occupying the channels when the members `are connected.

In the accompanylng drawings, Figure 11s a top View of a carriage pole constructed in z the structure where they come in contact with accordance with my invention. y Fig. `2 is a side view. Fig. 3 is an under side view. Fig. 4 is a central, longitudinal section of the pole. Fig. 5 is a horizontal, longitudinal section of the extremity of one of the arms. Fig. 6 is a View corresponding with Fig. 5 but illustrating the end ofthe arm. Fig. Gais a top view` of the arm constructed as in Fig. 6. Fig. 7 is a transverse section in the line 7.-7 of Fig. 5. Fig. 8 is a transverse section inthe line 8`8 of Fig. 6. Fig; 9 is a detached, perspective view of a filling block intended to be interposed between two channel-iron'portions of A represents the pole, which is ofg'wood,

with the usual top and bottom ironing and hood of the whiftietree, the `better t0 form a rigidly braced structure.

The members C C2 arearranged with their channels toward cach other 'and preferably with the edges of ytheir ianges in contact, as indicated in Fig. 7, and, for a suitable distance forwardly from their extremities they are bolted together by through bolts c c.

Forthe purpose of holding the two members more immovably in place and without Y possibility of vertical slip of one `member upon the other, the coincident channels, forming longitudinal openings in the arm where its members .are joined, are occupied by blocks D Ithrough which the bolts also pass. These blocks may-.be of wood or metal and may have any desired extent or length. If of wood they should be hard and `should be made originally large enough to require slight compression when the bolts c are screwed up. They` may also be in part'of Wood and in part of metal, if desired, in which case the parts at the extremities of the arms will be preferably of metal and will, moreover, be desirably provided with short bosses d d projecting` through the lateral walls of the members C C? and containing the through passage d for the shackle bolt, as plainly shown'in Figs. 5, 11 and l2. By this latter featureof construction said shackle bolt passage is made coutinuous and the bosses d tend to bring the joined members into exact relative position preparatory to bolting them, and serve also Vto retain them in such relative position should the clamping bolts c be'loosened.

In the use of channel-iron so light as may be used with ample strength,the aggregate width of the two pieces entering into. the

IOO

2 i v 524,823 V' several arms is somewhat less than the usual width provided between the ears of the shackles, and to give the extremities of the arms the desiredwidth, said two parts may be, as illustrated in Figs. 6, 6a' and '7, somewhat more widely separated at their extremities by making the terminal block D of tapering form, in which case said block should be provided with a tapering fin d2 upon its upper surface (and desirably also upon its lower surface) so as to iill the space which would otherwise be caused between the anges and to give a ilush and smooth surface.

At the point wherethe .members C2 join at their front ends with the pole, Wooden blocks D may be placed in the channels of said members to bear against the side surfaces ofthe pole and thus to iill the outer ends and give greater firmness. An ornamental effect is produced by extending these blocks beyond e the ends of the channel-iron members C2 and beveling or otherwise finishing their extremities, as indicated in Figs. l, 2 and 3. These filling blocksmay also, if desired, be extended beyond the point yat which the braces diverge from the pole and there provided with tapered fins D2, as for example, shown in the detached Fg- 10, and as may be supposed to v be shown in Figs. l and A3.

C3 is a third piece of channel-iron, curved at both its ends in the same direction with the channel outward, so as to bearin its central transverse portion against the forwardly directed flanges of the member C', at the middle of thelatter, and also with its flange edges against the inwardly directed flange edges of l the members C2 where it connects with them by a bolt.- This piece O3 may also be desirably extended at its extremitiesinwardly and rearwardly so as to bring the edges of its llanges against the sides of the tongue, to

which also it will be bolted, as shown in Figs.V

such prolonged portion be preferably pro` vided with the properly tapered fins d-2 rising to the outer surface of the fianges and giving a neat, flush inish.

The extension of the filling blocks beyond the points of divergence of a channeled member with the pole or with another channeled member has the advantage of preventing the hairs 'of horses tails from catching in the crotches of the pole and being drawn out, while the addition of the fins improves the neatness of the iinish. If these considerations are, however, to be disregarded and only thestrength which these filling blocks give Ibe required, they may be without such fins These blocks may be or such extension without departure from the general invention.

Under the term channel-iron herein employed it will be understood that steel or any other suitable metal may be employed, the term having special reference to the sectional form of the `metal familiarly known as channel-iron. 'It is to be understood that the exact form of the channel-iron portion of' the structure shown is not material and that variations in details may be made without departure from the invention.

I claim as my invention- 1. A carriage pole having each o'f its arms composed of two channel-iron members arranged channel'to channel and bolted toget-her at their extremities, one of said members being carried inward-and connected with the pole proper at or near its end and the otherdiverging therefrom forwardly and connected with the side of the pole, lcombined with filling blocks inserted in the channels of the members where they 4connect with 'each other or with the pole.

2. In combination with Ythe members C C2 severally connecting with the pole at diferent points in its length and brought together at their rear extremities to Vform the arms C, and arranged channel to channel, `filling blocks D at the extremities of the .arms provided with bosses d containing the through openingsfor the shackle biolts,

.3. In ,combination with the .channel-iron members and the pole, interposed filling blocks D occupying thelaterally closed channel spaces and prolonged beyond the points of .divergence of the said members.

4. In combination with afpole and channeliron arms composed each of the members C and C2 joined at their rear extremities and diverging into connection with the pole at different points in its length, filling blocks occupying the laterally closed channels of the irons, said blocks being prolonged beyond the points of divergence of the members and provided with fins rising flush with theouter ysurfaces of the flanges of said irons.

A5. -In combination with a pole and the arms composed of the, members C vC2 of channeliron arranged channel to channel and lconnected with each other and with the pole, substantially as described, of the channel-iron member C3 having av central transverse portion Vjoined with the transverse portion of the member C', channel to channel, and deiiected into connection with the members G2, channel to channel.

6'. The combination with a pole and arms composed of the channel-iron members C O2, connected and divergent, ,as shown, of the channel-iron member C3 having atransverse portion Iconnected with the transverse .portion of the member C', channel to channel,

and deflected forwardly into connection with the arms C2, channel to channel, andrearwardly into connection with the pole with the channels thereof toward the pole, and in- IOC IIO

lIn testimony that I claim the foregoing as my invention I aiiix my signature in presence of two witnesses.
